Percentile Values of Physical Fitness Levels among Polish Children Aged 7 to 19 Years--a Population-Based Study.

AIM

The objective of the study was to report gender and age-specific percentile values for fourteen commonly used field-based physical fitness tests among a national representative sample of Polish children aged 7 to 19 years.

METHODS

A descriptive cross-sectional and population-based study examines the physical fitness among a random and large national representative sample of schoolchildren aged 7 to 19 years in Poland. A sample of 49,281 children and adolescents (25,687 boys and 23,594 girls) was assessed by the EUROFIT fitness test battery, the International Committee on the Standardization of Physical Fitness Tests and Cooper Test of physical fitness. The LMS statistical method was used.

RESULTS

Smoothed gender and age-specific percentiles for the physical fitness tests in boys and girls aged 7 to 19 years are reported and expressed as both tabulated and curves values (2.3rd, 9th, 25th, 50th, 75th, 91st, and 97.7th). Figures showed greater physical fitness levels in boys, except for the flamingo balance, sit-and-reach, and stand-and-reach tests, in which girls performed slightly better. There was also a trend towards increased physical fitness levels as the age increased in both boys and girls.

CONCLUSION

The percentile values provided will enable the correct interpretation and monitoring of fitness status of Polish children.
